Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a mouthpiece for an aqualung and a method of using the same.

Conventionally, conversation devices have been known for aqualungs (sport divers). In such underwater telephones, a microphone is provided in the diving mask, by means of which the diver can communicate with his mothership or with other divers via the microphone lead. There are also devices in use that operate using ultrasonic waves and allow one person to wirelessly communicate underwater. Such equipment is very expensive and is rarely used in aqualungs.

The Aqualung's equipment usually consists of a translucent mask and seven or two compressed air cylinders, from which the hydrologist receives the necessary breathing air via a valve and an automatic lung connected to it.

For this reason, young divers have a mouthpiece that can be placed in their mouths, and divers hold this mouthpiece by biting it with their teeth. Therefore, bathers are unable to hold a full conversation because they can hardly close their lips.

Even when a diver speaks, the sound waves are slightly attenuated and distorted in the water.

For this reason, young people communicate with each other using sign language, but this sign language is limited to emergencies.

An object of the present invention is to create a device that allows divers to communicate with each other through conversation in a short period of time.

According to the invention, this object is achieved by a mouthpiece as defined in the characterizing part of claim 1.

In accordance with the present invention, a mouthpiece with a diaphragm allows the diver to breathe and speak, and an air-filled hose communicating with the mouthpiece and closed at the end with a closed diaphragm conducts sound waves. If the other diver holds the diaphragm to his ear, he can understand the conversation. It has also been confirmed that the trench can function with a helmet belonging to insulating clothing. The mouthpiece and hose according to the invention form part of the compressed air diving equipment so that young divers can disembark and communicate with fellow divers during their stay underwater.

A mouthpiece with a diaphragm can also be connected to a snorkel, in which case the free end of the snorkel tube connected to the hose can be selectively It has a diaphragm that opens and closes the opening.

It is important that large air bubbles do not form during the conversation. This is because these large bubbles are transposed by sonic vibrations in the rhythm of the bubbles escaping the spoken word, impairing communication.

Embodiments of the present invention shown in the drawings will be described below.

The mouthpiece shown in FIGS. 1-3 differs from previously known mouthpieces in that it includes a diaphragm that allows the user to speak.

This mouthpiece carries a connecting tube l leading to an automatic lung (not shown in FIGS. 1 to 3). This short connecting tube / transforms into one fork-shaped projection, which is provided with a biting projection 2 / at its outer end. A second connecting tube 3 for a corrugated hose communicating with the hollow space of the connecting tube is provided next to the connecting tube.

The fork-like projection is flared at a location 22 at its rear end. The front end of the fork-like protrusion is a connecting short pipe/
The two diaphragms are stretched.

For ease of illustration, the diaphragm 1 is represented by a dotted surface in FIG. 82. This diaphragm
When the user puts the mouthpiece into his or her mouth, the back side ends in the range of the user's lips.

In order to enable the user to open and close both diaphragms l in a valve-like manner with the lips, both fork-shaped protrusions 2 have a cross-sectional shape that tapers inwardly as shown in FIGS. 1 and 3. I'm going to do it.

The entire mouthpiece is made from a very soft synthetic resin or rubber elastic body, and the steel wire is embedded in the synthetic resin!
It is reinforced with. In FIG. 3, the closed state of the diaphragm I is indicated by dashed lines.

Based on FIG. 1, the mouthpiece M is combined with an automatic lung t and a rubber corrugated hose 7, which serves as a sound conductor and is closed by a diaphragm r.

In FIGS. &A, the closing diaphragm g is shown on an enlarged scale with part of the corrugated hose 7 connected thereto.

A pressure hose 4/ is connected to the automatic lung t, and a pressure hose 61
supplies air from the air storage cylinder to the automatic lung via a pressure reducing valve (not shown). A distribution chamber 63 is connected to the breathing valve 6 of the automatic lung t, and this distribution chamber 63 allows exhaled air to flow out to the outside in order to prevent air bubbles from obstructing the person's view. A small opening is provided in the distribution chamber 63 to prevent the formation of large bubbles. Figures 1 and 70 show a dispensing chamber as will be described later.

A hook 71 is provided at the end of the corrugated hose 7 near the diaphragm, and when the corrugated hose 7 is not in use, it can be hung onto the pressure hose 61 as shown by the broken line in the figure.

FIG. 7 shows the use of the mouthpiece M1, which is slightly different from the mouthpiece according to FIG. This mouthpiece M1 corresponds to the construction of the mouthpiece according to FIG. 1 and FIG. 3, except that it does not have a lateral connecting tube 3.

In this case, a corrugated hose 7 serving as a sound wave conductor is connected to the distribution housing 4tl for the discharged air.

In FIG. 7, there is a corrugated hose 7 at the right end of the distribution casing 44 (and a first breathing valve 6 at the other end!), which allows air to flow out but prevents water from entering the casing. This breathing valve 6.5 is provided with a porous cap to prevent the formation of large air bubbles. This cap is shown in a checkered pattern. .

FIG. r further shows a third usage state of the mouthpiece. This mouthpiece M5 almost corresponds to the structure of the mouthpiece based on Figs. iI
J does not have a connection point R leading to the lungs and connects to the short tube 3
A corrugated hose 7 leading to the snorkel pipe is connected to a corresponding short connecting pipe.

Furthermore, a breathing valve 6S is provided below the mouthpiece M5, and this breathing valve 65 allows breathing during conversation and drains water that has entered the snorkel.

The outer end of the snorkel tube is provided with a diaphragm chamber 10 for selectively freeing and closing the snorkel tube end.

FIG. 1A shows this diaphragm chamber 10 in cross section, and specifically shows the diaphragm chamber in a state where the side rotor 1 of the snorkel tube is closed.

Figure gB shows the diaphragm chamber io with the lower opening of the snorkel pipe open.

When the snorkel is filled with air in the closed state, the diver can speak due to the mouthpiece and communicate with fellow divers for short periods of time under the water. In the open state, the snorkel can be used as before.

2 and 10 show a discharge air distribution chamber 66 corresponding to the distribution chamber 63 shown in FIG.

This distribution chamber 6A is provided on both sides with a series of small air outlet openings 67 on the upper side and on the lower side! It has two large lateral air outflow openings 6g. There is a collar part 69 on the rear side of the distribution chamber 66, and this collar part 69 is sized so that it can be placed over or attached to the breathing valve of the automaton (6 in the figure). There is.

The right half of the diagram shows the distribution chamber 66 in use during conversation.
is shown in cross-section. That is, only a small amount of air is pressed during the conversation, so that the distribution chamber 6A is only about half filled with air. Air compressed during conversation escapes through small openings 67, forming a large number of small bubbles that do not impair communication. When the water person takes a deep breath and thus a corresponding amount of air is forced out, the water is expelled from the distribution chamber 66, so that this large amount of air can be evacuated without hindrance through the large opening at the bottom. .

Figures 1/ and 7.2 show the simplest mouthpieces that are particularly suitable for use with snorkels. The diaphragm lIo, which is directly connected to the connecting short pipe /θ0, is in the form of an oblong hose piece. Connection short pipe 100. Fork-shaped protrusion. , bite process, 210 and diaphragm hiro. Since it forms an integral part, such a mouthpiece can be manufactured inexpensively.

Diaphragm Hiroshi is shown in the first figure. The closed state of is shown by the dashed line.

When speaking, only the ends of the oblong hose sections q, o are present in the mouth in the area of the lips (see FIG. 73). The biting protrusion 0 is retained in the mouth during breathing.

11A, FIG. 76 shows a modification of the mouthpiece shown in FIG. 1, and FIG. 5 shows a modification of the mouthpiece. The fork-like protrusion is made of a correspondingly curved stainless steel FF1200 which is moored to a short tube. stainless steel wire 2
The free end of 00 is provided with a biting projection 2// made of synthetic resin. Diaphragm Hiromu. 0 is in the form of an oval hose piece, which continues to the connecting short pipe/ and surrounds the outside of the fork-like protrusion, 20Q, made of stainless steel wire, 2oo.

The equipment described above can be used without problems by experienced divers. The mouthpiece of the present invention differs from conventional mouthpieces in that it has an integral diaphragm and allows breathing in the same way as conventional mouthpieces.

Compared to conventional mouthpieces, the mouthpiece of the present invention has
The diaphragm can be moved by the movement of the lips, which has the great advantage of allowing full conversation. As mentioned above, since the mouthpiece of the present invention allows normal breathing, it can also be used for so-called exchange breathing.

In that case, two or more water-tight people are breathed alternately in seven diving devices. In the event of a failure, in which case air storage occurs, the diver whose diving equipment is still in good working order can remove his mouthpiece and supply it to another diver. That is, the two divers alternately receive breathing air from normal water equipment.

Another advantage of the invention is that, as already mentioned above, the mouthpiece with corrugated hose and diaphragm forms an integral part of conventional diving equipment. Complete water equipment these days always includes a snorkel. Traditionally, snorkels are used to store air from diving equipment before diving activities or to breathe on the surface in emergencies.

A snorkel with a mouthpiece and a diaphragm chamber according to the invention allows underwater communication. In cases such as the exchange breathing described above, the diver removes the normal mouthpiece connected to the diver's lungs and inserts a snorkel mouthpiece in order to enable the diver to communicate with fellow divers. Therefore, it is assumed that the diaphragm chamber of K is closed and the water present in the snorkel is blown out.

When blowing out water, the water flows through the breathing valve 65 installed in the mouthpiece.
is discharged from. Such use of a snorkel is not a problem for experienced divers and is within the range of habit.

FIG. 13 shows such a state of use.

The mouthpiece Mll used corresponds to the mouthpiece in Figure I// and Figure 12. The corrugated mouth 7 of the snorkel abuts the mouthpiece Ml+ via an intermediate piece in which a valve 6.3 is provided. The diver on the right side of the figure tries to communicate slightly with his companion on the left side of the figure. The diaphragm chamber 10 is placed against the listener's ear. Furthermore, the fa water equipment is connected to the automatic lung and has a sonic conductor,
It consists of a conventional diving device with a corrugated hose and a mouthpiece with a diaphragm or with an automatic lung and an auxiliary snorkel with a mouthpiece, a diaphragm chamber and a breathing valve according to the invention.

As an exception, iW water equipment can have elements of both. This allows divers so equipped to communicate through conversation with fellow divers who have the only conventional diving equipment. As a result of the experiment, it was confirmed that the listener's diver was able to communicate very well through conversation when he had a helmet made of neoprene.
